Stigma of People with HIV/AIDS in Sub-Saharan Africa: A Literature Review
Ngozi C. Mbonu,Bart van den Borne,Nanne K. De Vries
Journal of Tropical Medicine , 2009, DOI: 10.1155/2009/145891
Abstract: The aim of this literature review is to elucidate what is known about HIV/AIDS and stigma in Sub-Saharan Africa. Literature about HIV/AIDS and stigma in Sub-Saharan Africa was systematically searched in Pubmed, Medscape, and Psycinfo up to March 31, 2009. No starting date limit was specified. The material was analyzed using Gilmore and Somerville's (1994) four processes of stigmatizing responses: the definition of the problem HIV/AIDS, identification of people living with HIV/AIDS (PLWHA), linking HIV/AIDS to immorality and other negative characteristics, and finally behavioural consequences of stigma (distancing, isolation, discrimination in care). It was found that the cultural construction of HIV/AIDS, based on beliefs about contamination, sexuality, and religion, plays a crucial role and contributes to the strength of distancing reactions and discrimination in society. Stigma prevents the delivery of effective social and medical care (including taking antiretroviral therapy) and also enhances the number of HIV infections. More qualitative studies on HIV/AIDS stigma including stigma in health care institutions in Sub-Saharan Africa are recommended.
Gender-related power differences, beliefs and reactions towards people living with HIV/AIDS: an urban study in Nigeria
Ngozi C Mbonu, Bart Van den Borne, Nanne K De Vries
BMC Public Health , 2010, DOI: 10.1186/1471-2458-10-334
Abstract: We conducted in-depth semi-structured interviews, lasting 60 to 90 minutes, with 100 persons (40 members of the general public, 40 HCPs and 20 PLWHA) in Port Harcourt, Nigeria. The interviews were tape-recorded and transcribed verbatim. The Nvivo 7 computer package was used to analyze the data.There are similarities and differences between the general public and HCPs towards PLWHA in gender-related beliefs and reactions. For instance, although association with promiscuity and power differences were commonly acknowledged in the different groups, there are differences in how these reactions are shown; such as HCPs asking the female PLWHA to inform their partners to ensure payment of hospital bills. Women with HIV/AIDS in particular are therefore in a disadvantaged position with regard to the care they receive.Despite the fact that men and women with HIV/AIDS suffer the same illness, clear disparities are apparent in the negative reaction women and men living with HIV/AIDS experience in society. We show that women's generally low status in society contributes to the extreme negative reactions to which female PLWHA are subject. The government should create policies aimed at reducing the power differences in family, society and health care systems, which would be important to decrease the gender-related differences in stigma experienced by PLWHA. Interventions should be directed at the prevailing societal norms through appropriate legislation and advocacy at grassroots level with the support of men to counter laws that put women in a disadvantaged position. Furthermore, development of a policy that encourages equality in access to health care for all patients with HIV/AIDS by applying the same conditions to both men and women in health care institutions is recommended. There is a need to protect women's rights through implementing support policies, including paying attention to gender in the training of HCPs.Women and girls continue to be affected disproportionately by H

Abstract: With the objective to create technologically advanced materials to be scientifically applicable, dual-layer silica alumina membranes were molecularly fabricated by continuous surface coating silica layers containing hybrid material onto a ceramic porous substrate for flue gas separation applications. The dual-layer silica alumina membrane was prepared by dip coating technique be-fore further drying in an oven at elevated temperature. The effects of substrate physical appear-ance, coating quantity, cross-linking agent, number of coatings and testing conditions on gas separation performance of the membrane have been investigated. Scanning electron microscope was used to investigate the development of coating thickness. The membrane shows impressive perm selectivity especially for CO2 and N2 binary mixture representing a stimulated flue gas stream.

Journal of Geoscience and Environment Protection (GEP) , 2017, DOI: 10.4236/gep.2017.510001
Abstract: The impact of human activities on sensitive watershed terrains is a critical consideration in the management of urban ecosystems. Degradation of sensitive ecosystem features such as watershed land areas is often irreversible due to the extent and intensity. The vulnerability of 150 m watershed management zone of Otamiri river Owerri Imo State, Nigeria was studied by topographic analysis using 1977 digital elevation model (DEM), 1977 aerial photos, Shuttle Radar Topographic Mission DEM of 2000, 2012 satellite imagery and the 2016 Master Plan of the study area. The impact of human activities in elevation change was observed in the parts of substantial human activities while topographical stability was recorded for areas of very low human activities.

Italian Journal of Pediatrics , 2010, DOI: 10.1186/1824-7288-36-53
Abstract: To determine the prevalence of psychosocial dysfunction and depressive symptoms among adolescents who abuse substance and also note the influence of socio-demographic factors and type of substance on the pattern of dysfuction.A cross-sectional study was carried out among 900 adolescents selected from 29 secondary schools in Enugu metropolis. A multi-stage sampling procedure was used to select the students. The student drug use questionnaire was used to screen respondents for substance abuse. Those who were abusing substance and matched controls (non substance abusers) were assessed for psychiatric symptoms using the 35-item Paediatric Symptom Checklist (PSC) and the Zung Self-rating Depression Scale (SDS). Social classification was done using the parental educational attainment and occupation.A total of 290 students were current substance abusers. The substances most commonly abused were alcohol (31.6%), cola nitida (kola nut) (20.7%) and coffee (15.7%). Using the PSC scale, 70 (24.1%) subjects compared to 29 (10.7%) of the controls had scores in the morbidity range of ≥ 28 for psychosocial dysfuction. This was statistically significant (χ2 = 17.57 p = 0.001). Fifty-four subjects (18.6%) had scores in the morbidity range of ≥ 50 for depressive symptoms using the Zung SDS compared to 21 (7.7%) of controls. This was statistically significant (χ2 = 14.43, p = 0.001). Prevalence of dysfunction was not significantly related to age in both subjects and controls (χ2 = 4.62, p = 0.010, χ2 = 4.8, p = 0.10 respectively). Also using both scales, there was no significant relationship between psychosocial dysfunction and gender or social class in both subjects and control. The prevalence of dysfuction using both scales was significantly higher in multiple abusers compared to single abusers. Subjects abusing alcohol scored more on both scales compared to those abusing other substances.Prevalence of psychosocial dysfunction is higher in adolescents abusing substance compare to con

Academic Research International , 2012,
Abstract: This paper investigated the influence of occupation on women’s attitude towards oral health among women attending the primary health care (PHC) centres in Nkanu West Local Government Area of Enugu State. The findings of the study revealed that the respondents agreed that occupation influences the attitude of women towards oral health, also it was identified that the influence was negative. Based on the findings it was observed that it has a serious health implication on maternal and child health. Recommendations were made that women should be enlightened more on the influence of occupation on their oral health.Further more, that women should be sensitized on the need to prevent oral health problems.

Energy and Power Engineering (EPE) , 2015, DOI: 10.4236/epe.2015.79039
Abstract: A tubular commercial mesoporous support was used to prepare a Pt impregnated membrane using the reservoir method and tested for moderate temperature (300°C) gas transport of hydrogen (H2), helium (He) and nitrogen (N2) gas molecules. H2 and N2 gas permeation of 6.1 and 4.5 l/min at 1.0 barg feed pressure and 25°C respectively was obtained from the support. On the other hand, H2 and N2 gas permeation of 4.6 and 1.7 l/min at 1.0 barg feed pressure and 25°C respectively was also obtained from the Pt membrane. Selectivity of H2 over He of 1.96 at 300°C and 1.6 barg for the Pt membrane was obtained and found to be higher than that of the theoretical Knudsen selectivity. Also, a selectivity of H2 over N2 of 2.72 at 25°C and 1.0 barg was obtained and found to be close to that of the theoretical Knudsen selectivity. The gas permeation and the selectivity performance of the membrane were evaluated.
RADIO FREQUENCY TRANSCEIVERS: A BETTER REPLACEMENT FOR DATA CABLES IN COMPUTER BASED DOT MATRIX DISPLAY SYSTEMS
Mbonu E.S., Uzedhe G.O., Nwafor C. M.
Academic Research International , 2012,
Abstract: This paper highlights the disadvantages of using data cables in interfacing dot matrix display to computer and proposes a better method of doing the same. The method being used presently utilizes cables as links between the computer and the display unit. These cables have drawbacks associated with them. Among these drawbacks are signal losses or attenuation, difficulty in deployment, troubleshooting and maintenance. These contribute to the high cost of implementation especially in a situation where multiple displays are to be installed. The Radio Frequency (RF) transceiver presented in this paper has a number of features that eliminate totally the problems associated with the use of data cables. These features include in-built error checking capability, high sensitivity and long transmission range, self controlled protocol translation that is easy to use, standard UART interface that is compatible with microcontrollers among others. Multiple displays can also be controlled by a single host computer because the RF has both multiplechannels and baud rates. Visual basic (VB).net is employed to develop the graphical user interface used in the implementation of the new proposed system. Communication is made through the RS232 interface protocol between the computer and RF transceiver. ATMEL microcontroller that supports serial communication, interfaced with liquid crystal display and non-volatile RAM, is used to demonstrate how the RF transceivers work.
Sorption Kinetics, Intraparticle Diffusion and Equilibrium Partitioning of Azo Dyes on Great Millet (Andropogon sorghum) Waste Biomass

Journal of Applied Sciences , 2007,
Abstract: Azo dyes are environmental pollutants and they are recalcitrant to decolorization by photo degradation and other conventional methods of treatment. The adsorption kinetics, intraparticle diffusion and equilibrium partitioning of Methyl Orange (MO), Methyl Red (MR) and Methyl Blue (MB) onto andropogon sorghum waste biomass was studied. As time increased the amount of the dyes adsorbed increased and equilibrium was reached within 40-50 min. Modification of the adsorbent by carboxymethylation and thiolation enhanced the adsorptive capacity of the adsorbent. The kinetics of sorption was well correlated using the pseudo-second order rate equation. The pseudo second order rate constant ranged from 0.742 (g mg-1-min) for Methyl Orange (MO) on thiolated sorghum to 5.741 (g mg-1-min) for Methyl Blue (MB) on carboxymethylated sorghum. The mechanism of sorption was found to be intraparticle diffusion controlled and the intraparticle diffusion rate constants ranged from 0.0969 min-1 for Methyl Red (MR) on thiolated sorghum to 0.8298 min-1 for Methyl Red (MR) on carboxymethylated sorghum. The boundary layer diffusion effects were calculated. The very high values of correlation coefficients (R2) obtained showed that these models fit the experimental data perfectly. Therefore andropogon sorghum was found to be a good adsorbent for adsorptive decolorization of Azo dyes from waste water.
